Abstract: An experiment to search for superdeformation in $^{144}$Gd was performed using the $^{100}$Mo($^{48}$Ti,4n)$^{144}$Gd reaction at 221 MeV. The beam was delivered by the tandem accelerator at the INFN/LNL at Legnaro, $\gamma$-radiation was measured with the GASP array consisting of 40 compton supressed germanium detectors. A new superdeformed band was found and clearly assigned to $^{144}$Gd. This band shows a strong backbending in the J$^{(2)}$ moment of inertia at a rotation energy of 0.4 MeV. In good correlation with theoretical predictions this effect was interpreted as a crossing of proton quasiparticle levels. A search for linking transitions out of the superdeformed band in $^{144}$ Gd was performed by summing each two $\gamma$-energies in coincidence with the band. Several candidates for two-step decay transitions were found and a absolute energy assignment for the band was made. Also possibilities for the absolute spins could be set up. A software package for sorting data delivered by second generation spectrometers was developed and documented.
